Construction walls have been removed around the site of Antarctica -- Empire of the Penguin at SeaWorld Orlando. Theme-park guests could get a peek but not enter the area, SeaWorld's largest expansion in its history, on Sunday.

Antarctica is scheduled to have its grand opening to the public on Friday, May 24. No "soft openings" or previews have been announced, although private events and a media preview are scheduled before Friday. An opening ceremony is set for 8:45 a.m. Friday.

So, what's inside? The centerpiece is a dark ride that follows Puck the penguin's growth. Ride vehicles are essentially small motion simulators that glide along wirelessly and track-free. The attraction winds up with a penguin habitat (temperature: 30 degrees Farenheit). Nearby are a restaurant and eating areas based on the life of researchers in Antarctica plus a gift shop that, just to shake things up, isn't attached to the ride exit. A visual highlight is a wall that includes carvings of the world's varieties of penguins and a South Pole photo op.
